I did post within your post, but even though I tried to make it bold print, it didn't come out that way.
I said that having your girls go to counseling is not about telling them that there's nothing wrong with the situation (separation and devorce) -- it's about helping to provide them with appropriate coping mechanisms to handle their emotions. This is not the only painful time they will ever have in their lives, and the better they're able to cope with pain, the better their quality of life will be.
I also posted that it's good that you realize you're not up to the task of home schooling.
